gw2011 · Answer

Let c=carpenters salary
Let cp=computer programmers salary

cp=2c-7690

2c-7690+c=99,830
2c+c=99,830+7690
3c=107,520
c=$35,840  This is the carpenters salary

cp=2c-7690
cp=(2)(35,840)-7690
cp=71680-7690
cp=$63,990  This is the computer programmers salary

Therefore, the computer programmers salary is $63,990 and the carpenters salary is $35,840
